Parking Space Reassignment for EV Charging-Discharging Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parking lots with storage batteries struggle to coordinate electricity demand with facilities, as vehicles parked in the same space for extended periods disrupt the balance between charging and discharging capabilities, leading to inefficiencies in power supply.
Innovation Solution
A parking management system with multiple parking spaces, including a first and second parking space, utilizes information management sections to determine vehicle conditions and space availability, facilitating the movement of vehicles between spaces to optimize power supply and demand, using a communication network and integrated parking management device to coordinate the movement of vehicles based on battery storage ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicles are parked in the same parking space for an extended period of time, then the parking management becomes simpler, but the parking lot cannot coordinate well with the electricity demand of the facility
Solution Approach 1:
The system dynamically reassigns vehicles between parking spaces based on real-time electricity demand conditions. The determination section continuously monitors whether discharge spaces are available and whether vehicles meet discharge conditions (battery charge level, discharge capability), then automatically generates movement instructions to optimize the distribution of vehicles across charging and discharging spaces, enabling the parking lot to adapt flexibly to varying power demand requirements.
2Adaptability or versatility
If vehicles are moved between parking spaces to optimize power supply, then coordination with electricity demand improves, but the system complexity increases
Solution Approach 1:
The parking lot is segmented into functionally distinct charging spaces and discharging spaces. The management system is divided into separate components: a determination section that assesses discharge space availability and vehicle discharge conditions, and a movement instruction generation section that executes reassignment. This segmentation allows the system to manage complexity through modular functional decomposition while maintaining effective coordination with electricity demand.
Solution Approach 2:
The system implements feedback loops where the determination section continuously monitors the current state of parking spaces and vehicle conditions, compares this with electricity demand requirements, and adjusts vehicle assignments accordingly. The movement instruction generation section receives feedback on discharge space availability and vehicle discharge capability, enabling dynamic optimization that adapts to changing conditions without requiring overly complex centralized control.
3Loss of energy
If vehicles with suitable battery conditions are moved to specific spaces, then power transmission losses are reduced, but the difficulty of detecting and measuring vehicle conditions increases
Solution Approach 1:
Vehicles self-report their battery conditions (charge level, discharge capability) to the parking management system through onboard communication interfaces. This self-service approach eliminates the need for complex external detection equipment, as vehicles autonomously provide the necessary information about their power supply and discharge conditions, enabling the determination section to efficiently identify suitable vehicles for discharge space assignment without increasing measurement complexity.

AI summary
A parking management system comprises a first information management section that manages first parking information related to parking in the first parking space and first vehicle information related to vehicles parked in the first parking space; a second information management section that manages second parking information related to parking in the second parking space and second vehicle information related to vehicles parked in the second parking space; a condition determination section that determines the existence of a space condition in which a parkable space exists in the second parking space based on the second parking information of the second information management section, and determines the existence of a movable condition where a movable vehicle exists in the second parking space based on the first vehicle information of the first parking management section.
